I’d suggest you to re-flash the board and to install the packages one by one instead of the upgrade command, because it will install all the packages you have installed that are upgradable and that will take a lot of extra space.

Re-flash your board.

Add the repos into the base-feeds.conf. Actually you only need to add the core2-32 since all the packages are included in there.

I think it was step 6. The actual document mentioned there was to switch to a larger kernel, but the first several steps have to do with how to increase the size. So I do that now as soon as I install on any new Edison. Since doing that I have not run into this issue.

I also have it in my kernel install guide (step 2), however simsiss0722, I don't recommend you to run "opkg upgrade" against my repo, because of exactly such effects (and later on you;d run out of space on rootfs as well ). It's not the use case I intend it for. You better pick specific packages you want to upgrade and do that with "opkg install".
